You are getting bored as you are stuck at home, and want to find out the effective 'spring constant' of random objects. You find a spare sock seems to stretch nice and easily. So you place a roll of quarters in your sock (approximate mass 0.23 kg) and notice that it stretches about an inch --- 2.54cm . What is the spring constant of your sock (in N/m)
